For the first time, scientists have experimentally demonstrated that sound pulses can travel at velocities faster than the speed of light, c. William Robertson’s team from Middle Tennessee State University also showed that the group velocity of sound waves can become infinite, and even negative.

I'm not a physics expert, so I'm not sure what to make of this.. But it happened at my university, so here it is.

Thats awesome! Props to MTSU!
